Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The transcript levels of 560 genes were decreased (less than two-fold), while those of 312 genes were increased (more than two-fold) in the KO-HsfA1d/A1e plants compared with the wild-type plants. The transcript levels of HsfA2, HsfA7a, HsfA7b, HsfB1, and HsfB2a were down-regulated in the KO-HsfA1d/A1e
Publication Title
HsfA1d and HsfA1e involved in the transcriptional regulation of HsfA2 function as key regulators for the Hsf signaling network in response to environmental stress.

Description
Plants possess highly sensitive mechanisms that monitor environmental stress levels for a dose-dependent fine-tuning of their growth and development. Differences in plant responses to severe and mild abiotic stresses have been recognized. Although many studies have revealed that glutathione can contribute to plant tolerance to various environmental stresses, little is known about the relationship between glutathione and mild abiotic stress, especially the effect of stress-induced altered glutathione levels on the metabolism. Here, we applied a systems biology approach to identify key pathways involved in the gene-to-metabolite networks perturbed by low glutathione content under mild abiotic stress in Arabidopsis thaliana. We used glutathione synthesis mutants (cad2-1 and pad2-1) and plants overexpressing the gene encoding gamma-glutamylcysteine synthetase, the first enzyme of the glutathione biosynthetic pathway. The plants were exposed to two mild stress conditionsoxidative stress elicited by methyl viologen (MV) and stress induced by the limited availability of phosphate. We observed that the mutants and transgenic plants showed similar shoot growth as that of the wild-type plants under mild abiotic stress. We then selected the synthesis mutants and performed multi-platform metabolomics and microarray experiments to evaluate the possible effects on the overall metabolome and the transcriptome. To understand the metabolic responses observed under mild abiotic stress, we conducted gene expression profiling by Affymetrix ATH1 GeneChip. pad2-1 and the wild type Col-0 samples were harvested at 18 day-old after germination under two different stresses, MV treatment and limited phosphorus conditions.

Description
Activation of telomerase often endows cancer cells, but rarely normal somatic cells, with immortality. Especially, fetal lung fibroblasts are known to be hardly immortalized by TERT overexpression. We here established an immortal non-transformed lung fibroblast cell line only by TERT transfection, as well as an immortal transformed cell line by transfection of TERT and SV40 early antigens. Comparing the expression profiles of these cell lines with those of mortal cell strains with elongated lifespan after TERT transfection, 51 genes, including 19 upregulated and 32 downregulated, were explored to be the candidates responsible for regulation of cellular proliferation of lung fibroblasts. These included the genes previously reported to be involved in cellular proliferation, transformation, or self-renewal capacity, and those highly expressed in lung tissues obtained from patients with idiopathic pulmonary fibrosis or hypersensitivity pneumonitis. This set of lung fibrobrast cell lines/strains of identical genetic background with different proliferative capacity, mortal and immortal non-transformed fibroblasts may become useful model cells for research on lung fibroblast growth regulation and the candidate genes explored in this study may provide promising biomarkers or molecular targets of pulmonary fibrosis.
